Dielectric barrier discharge lamp with tube remnant discharge chamber connection

Abstract

To enable the easy and adequately reliable cleaning of the inner surface of the chamber material, and as a result, to provide a dielectric barrier discharge lamp with good lighting characteristics and simplicity of manufacture, a dielectric barrier discharge lamp having a discharge chamber with a cylindrical, double-tube construction with an outer tube and an inner tube, in which the cylindrical discharge space formed between the outer tube and the inner tube is filled with a discharge gas in which excimer molecules are formed by a dielectric barrier discharge, two or more fluid distribution tube remnants connecting to each discharge chamber. It is preferable that the dielectric barrier discharge lamp described above have two or more fluid distribution tube remnants formed on opposite ends of the discharge chamber.

What is claimed is:  
     
       1. A dielectric barrier discharge lamp having a discharge chamber with a cylindrical, double-tube construction comprising an outer tube and an inner tube, in which a cylindrical discharge space formed between the outer tube and the inner tube is filled with a discharge gas in which excimer molecules are formed by a dielectric barrier discharge; wherein the discharge chamber is formed with remnants of two or more fluid distribution tubes that connect to the discharge space of the discharge chamber. 
     
     
       2. A dielectric barrier discharge lamp as described in  claim 1 , wherein the two or more fluid distribution tube remnants are formed on opposite ends of the discharge chamber.
